FOUR-POINTED STAPLE.

SPECIFICATION forming part of Letters Patent No. 780,489, dated January 17, 1905.

' Application filed June 10, 1903. Serial No. 160,798.

ments in Four-Pointed Staples, of which the following is a specification. The object of my invention is to provide a fastening device for butter-tubs, boxes, bun gs,

and other articles in which two independent pieces of wood require to be held in a fixed relation to each other temporarily, and the,

form which I have adopted for such fastener is that of a four-pointed staple.

This device is very strong, the grip obtained by it is firm, and the device can be made very quickly and cheaply by striking up with a die from a continuous strip of boxstrap of suitable width. The box-strap which I prefer to employ is that known in the trade as the railway-strap, being a narrow strip with rounded edges and a flat middle portion slightly corrugated crosswise.

My improved staple is made in various sizes, and in the accompanying drawings I have shown the size which I consider best for butter-tubs.

Figure 1 is a plan of a piece of box-strap from which the staple is to be cut. Fig. 2 is an end view of the same. Fig. 3 is a. length cut therefrom by a suitable die. Fig. 4 is a side view of the four-pointed staple as formed by turning down the points of the device shown in Fig. 3. Fig. 5 is an end view of the same.

Same lettersindicate similar parts in the different drawings.

A is the box-strapping from which the staple is cut. This consists of the fiat middle portion a and the two side ribs 6 b, which are round and solid. As stamped out by the die, a portion of the center a at each end is cut away and the side ribs are cut tapering to form the staple-points c c c 0. These are afterward bent substantially at right angles to the body, as shown in Figs. 4 and 5.

This staple may be applied to fiat'surfaces which are to be joined together in the same plane by simply driving one end into the wood surface on one side of the dividing-line and the other end into the piece on the other side of the dividing-line. In securing the cover of a firkin', butter-tn b, box, or any other article to the side "or any two wooden pieces at an angle to each other one end of the staple is driven into one of the piecesfor example,"

the cover-while the'body of the staple is then bent to such an angle as may be required. to enable the other end to be driven into the other piece-for example, the side of the tub.

While the staple itself by reason of the grip obtained by the tapering prongs is a sufiicient fastening for all ordinary purposes, nails may, if desired, be driven through the body of the staple, which can readily be done without weakening the material.

When driving nails through the body portion of the staple, the corrugated surface thereof has the function of holding in a fixed location the point of a nail to be driven through said body portion, thereby rendering it more easy to drive the nail therethrough when found desirable to further secure the staple in this manner.

I claim A four-pointed staple consisting of a strip of thin metal whose surfaces are respectively, transversely corrugated and plain, the opposite edges of said strip being turned over upon orro ARENDT.
